Title: Numerical controller
Inventor: YAMAGUCHI TAKAHIRO
IPC: G05B19/4103
Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To ensure accuracy and to perform an interpolation of excellent working efficiency by outputting an infinite interpolation unit amount from a minimum value, selection part to an interpolation means or outputting an interpolation unit amount from an interpolation unit amount calculation means to the interpolating means. SOLUTION: The minimum value selection part 9 selects the smaller one of a critical interpolation unit amount u and the interpolation unit amount Δfi from the interpolation unit amount calculation means 4 and decides a limit interpolation unit amount v. This limit interpolation unit amount v is passed through a switch SW 3 and outputted to the interpolation means 10 as the interpolation unit amount Δfi. In the case that the critical interpolation amount u is smaller than the interpolation unit amount Δfi from the interpolate unit amount calculation means 4, the value of the cirtical interpolation unit amount u is selected and a point where an interpolation error becomes an allowable error εt is interpolated in the fraction processing of the interpolation means 10.  Inversely, in the case that the interpolation unit amount Δfi from the interpolation unit amount calculation means 4 is smaller than the critical interpolation unit amount u, the value of the interpolation unit amount Δfi is selected, however, the interpolation error becomes less than the allowable error εt even when interpolation is performed by the Δfi in the fraction processing of the interpolation means 10.

Title: Pretreatment for soldering
Inventor: KATO FUMIO
IPC: H01L23/48
Filed: 1984-10-11
Abstract: PURPOSE:To improve solderability and to facilitate mass production by forming preliminarily a thermally sprayed film of a conductive material having good wettability with solder to a lead wire. CONSTITUTION:Electronic parts are constituted of a heat radiating plate 1, lead wires for external connection having poor solderability and a resin package 3, etc. The conductive material 8 such as copper or nickel having good wettability with solder is thermally sprayed from a thermal spraying device 7 to the lead wire 2 for external connection to form a thermally sprayed film 9 on the surface thereof. The uniform film 9 is formed by rotating the electronic parts or turning the device 7 around the electronic parts. The lead wire 2 having the poor solderability has the good wettability with solder when the film 9 is formed thereon by the above-mentioned method. The solderability is thus improved and since the treating method is easy, the mass production is easy as well.

Abstract: PURPOSE:The titled transparent resin composition useful for, e.g., food containers and packaging materials or medical devices and appliances, prepared by mixing a polypropylene resin with 1.3,2.4-di(alkylbenzylidine)sorbitol and a specified metal lactate. CONSTITUTION:At least one metal lactate selected from Group II metal lactates (e.g., calcium lactate) and Group II metal alkyllactates (e.g., calcium stearyllactate) is used. Namely, 100pts.wt. polypropylene resin is kneaded with about 0.01-1pt.wt. 1.3,2.4-di(alkylbenzylidine)sorbitol and about 0.01-1pt.wt. said metal lactate. A molding of the obtained resin composition is excellent in transparency and when the molding is exposed to water, hot water, steam or the like, said sorbitol (as a clarifying agent) will not leach out of the molding. Thus its transparency can be retained for a long time and it is sanitarily safe.

Filed: 1991-08-23
Abstract: PURPOSE:To detect a moving area accurately even from a complicated picture by frequency-shifting an inter-frame difference of a picture signal and applying low frequency shift to a spatial high frequency component to detect motion. CONSTITUTION:A frame difference from a subtractor circuit 80 is given to a BPF 40, in which a high frequency component is extracted and it is subtracted from the original signal by a subtractor circuit 81 to extract a low frequency component, an absolute value circuit 61 takes an absolute value from the extracted component and the resulting signal is a motion detection signal. A multiplier circuit 70 multiplies a sinusoidal wave carrier with a high frequency component outputted from the BPF 40. The carrier frequency is to be selected near the center frequency of, e.g., the BPF 40. The high frequency component is divided into the component whose center is DC and the component whose center is a frequency twice the carrier frequency through the multiplication. An LPF 50 eliminates the latter frequency component. Thus, the component only whose center is DC remains and the original high frequency component is shifted to a low frequency area near the DC.
